The principal object of the invention is to provide elements of aflexible fibrous base water- .6 proofed and weatherproofed in anysuitable manner and so constructed as to render them suitable for use assiding material invplace of :wooden clapboard; brick, and similarrelatively expensivesiding. 0 ,In order to produce a satisfactory sidingmaterial of the character indicated that will be worthy as a substitutefor the materials named, the chief considerations are economy ofmanufacture and ease of application with a amount of material,consistent of course, with adequate protection and pleasing appearance.With the foregoing considerations in View, waterproof flexible fibrousmaterial, as ordinarily fabricated, for example, in the asphalt roofingindustry, is illadapted as a satisfactory siding material since therequirements of economy in application make it necessary when'laying'the material in overlapping rows on a vertical wall or the like,to arrange the rows with; considerable vertical distances between thesuccessive overlapping rows, that is to say with-relatively smalloverlap between successive 'rows. a consequence, the flexible nature ofthis type of material, renders the material "objectionable owing to thefact that these large exposed portions are easily blown outwardly bythe'wind and they become otherwise readilydisto'rted and unsightly, thefiabbiness of the material when exposed in large sections evidencing'itself more pronouncedly than is the case when relativelysmalleryertlcal sections are exposed as obtains on pitched roofs forexample.

' By my present invention, the material is so fashioned that theforegoinglobjections are overcome without substantial sacrifice of therequired-economy as heretofore mentioned.

In accordance with thefinventioml provide siding strips or" flexiblefibrous material suitably waterproofedI 'andin the-form of elongatedsubstantially rectangular body portion's'having' a centrally' locatedtongue or extensionalong the upper edgeof thejbody portion, the stripsas thus configured being adapted to be laid j overlapping rows'with' thelonger axisfof the portion in a horizontal direction; and with t tonguesextending upwardly so ith at .they will underlie the joints betweenadjacent strips in the nextwucceeding row; A f f 1 v importantfeatureoftheconstruction af- 3 'forded'by my inventionfthesiding' stripsconfiglowermost edg'egof thestrip.

By making thestrips of the aforedescribed, configuration and properly coordinatingthe dimensions thereof within the limits set forth, greater economy canbe effected since the body portions need be only slightly higher thanthe extent of vertical exposure, the tongues being of such height andwidth to provide the necessary protection at and around the jointsbetween the strips when laid.

These strips may be severed from continuous sheets of felted fibrousbase impregnated with waterproofing saturant such as molten asphalt, andcoated on one or both surfaces thereof with a layer of weatherproofmaterial such as high melting point blown asphalt within which may beimbeddedcomminuted or granular mineral material.

Instead of molten asphalt, the coating material applied to the surfaceor surfaces of the base may be in the form of an aqueous bituminousemulsion made with colloidal mineral emulsifying agent, such forinstance, as bentonite. A coating composition of this character isparticularly advantageous since the waterfree film thereof possesses thepeculiar characteristic of remaining in place without flow undertemperatures in excess of the meltingpoint of the bitumen, thusrendering the base more highly fireresistant.

Several modes. in which the strips, configured as above described, maybe severed from continuous sheets of the coated and mineral surfacedbase, are illustrated in Figures 5 and 6. In both of these methods, I-prefer to employ a sheet of base of a width equal to twice the maximumheight of. the strips. The sheet may be slitted longitudinally along itsmidportion, as

indicated at 20, (Figure 5) or 20a (Figure 6),,

and from each section thus formed, the strips may be severed withoutwaste by means of knives positioned for example, upon a cutting cylinderso as to sever the strips from these sections in reversely arranged orcomplemental fashion, as indicated by the lines 21 to 25 (Figure 5) or26 to 34 (Figure 6) defining the boundaries of the strips.

The strips thus severed from the sheet, when applied to the side wallsof a building with the greater part of the body portions thereofexposed, would be too flexible and flabby to serve as eflicient andattractive siding material. -In order toadapt the strips for thispurpose, I provide the body portions thereof with a weighting qr bulkingmedium preferably in the form of an additional layer 40 of waterproofcoating material and crushed mineral grit embedded therein. This bulkinglayer may, in some instances, be formed with the exposed face of thestrip, but preferably, as shown, it is applied to both the exposed andthe underface of the strips. This additional layer of coating andmineral grit may be applied in any convenient way, as for example, byimmersing the strips in a bath of the coating material. Upon withdrawalfrom the coating bath, the strips should be suspended in a substantialvertical position so as -to permit the viscous coating material to draindownwardly towards the lower edge thereof and build itself up in theform of tapered coating with maximum thickness adjacent the lower edge.After the coating material has been applied and permitted to drainsufficiently and take the desired taper, the coated strip may be thencontacted with a bed or shower or comminuted mineral matter such ascrushed slate or the like, of a color suitable for siding. Preferably,the additional coating layers as thus described, should extend to a lineslightlybelow "ing row to a point slightly below the edges 12 of theunderlying strips, and hence, the additional coating layer is preferablyand advantageously not extended above the line of exposure.

As will be observed, when the strips are severed from the sheet in themanner illustrated in Figure 5, the provision of the bulking layer orlayers necessarily constitutes a separate stage in the manufacture. Thiswill be apparent from Figure 5 wherein it will be noted that because ofthe reversed arrangement of the strips in each section formed by thelongitudinal slit 20, coating material could not very readily beconfined to the body portions of the strips in the sheet without alsoadditionally coating the tongues, and this is undesirable from the pointof view of economy as well as from the standpoint of construction,because of the desirability of having a strip with relatively thin.fiexible concealed portions and with only the exposed portions thereofbulked so as to produce the maximum weight at the lowermost edgesthereof. By cutting the strips from 'the sheet in the manner illustratedin Figure 6,

the bulking of the body portions of the strips may be effected as onecontinuous operation prior to the severance of the strips from thesheet. According to the arrangement shown in Figure 6, the cuttingoperationfor severing the strips from the sheet is designed to form thebody portions of the strips in longitudinal alignment and likewise thetongues of the strips, instead of forming in the same longitudinalalignment body portions and intervening tongues of other strips, as inthe arrangement of Figure 5. With this arrangement, therefore, I amenabled to confine the bulking operation to areas which are to form thebody portions of the strips. Thus, the additional coating material maybe applied to the sheet in longi tudinalbands, such bands being appliedalong each margin of the sheet and extending laterally of the sheet tolines, indicated at X, spaced slightly outwardly of the lines alongwhich the cuts 27 and 33 are to be made. A similar band of coatingmaterial is applied centrally of the sheet and extends laterally tolines indicated at Y, spaced slightly. inwardly of the lines along whichthe cuts 29 and 31 are. to be made, this latter band being substantiallydouble the width of the marginal bands, so that when the sheet is slitat 20a, the adjacent strips on either side of the slit 20a will carrythe bulking layer. These bands of coating material may be applied as bymeans of sprays or coating rolls, either to one or both faces of thesheet, and any convenient means may be coating material to the sheet inspaced longitudinal bands, an important feature is the confinement ofthe bands within the transverse areas of the sheet out of which the bodyportions of the strips are to be cut, so that the coating material willbe precluded from flowing over onto the portions of the sheet from whichthe tops of the tongues of the oppositely disposed strips are formed, inwhich event the additional coating layer along the topmost portion ofthe tongues would tend to elevate the overlying strips at these points,when laid, thereby detracting from the sightliness of the completed sidewall construction.

The strips formed by either of the methods herein described will bearranged in successive overlapping rows with the strips of each rowbreaking joints with those of the preceding row, as shown in Figure 3,and with the lower edges 17 of each strip spaced a slight distance belowthe upper edges 12 of the body portion of the strips ,in the nextpreceding row so as to expose the greatest part of the body portion, asis necessary in order to realize the required economy. By virtue of thefact that the tongues 13 are equal in height to the body portion, theamount of vertical overlap between succeeding rows will leave an equalvertical portion of the tongues to project above the upper limit of thejoints between adjacent shingles in the next succeeding row suflicientto preclude leakage there- I through.

In applying the strips to the side wall of a building, I prefer thatthey be fastened thereto by nails driven through the strips at pointsslightly below the upper margin of the bulking layer 40, and in positionto be concealed by the overlying strip. By thus nailing the stripsthrough the thickened portions thereof, instead of through the portionsnot formed with the bulking layer, greater resistance is offered toraising or blowing up of the exposed portions under the action of thewind.-

Having thus described my invention, it will be manifest that numerousvariations and changes maybe made therein without departing from thespirit of the invention as set forth in the appended claims.
